bindPort()

void TTAMachine::HWOperation::bindPort ( int  operand, const FUPort &  port  )

virtual

Binds the given operand of the operation to the given port of the function unit.

If the given operand is already bound to another port, the old binding is replaced with the new one.

Parameters

operand	Index of the operand.
port	The port.

Exceptions

IllegalRegistration	If the given port does not belong to the same function unit as this operation.
ComponentAlreadyExists	If the given port is already reserved for another operand.
OutOfRange	If the given operand is less than 1.

slack()

const

Returns the slack of the given input.

The slack tells how many cycles AFTER the trigger, opcode-setting move is scheduled, can the operand be scheduled (and still affect correctly the result of the operation).

Parameters

Returns

The slack of the given input.

Exceptions

IllegalParameters
